Aging is a major risk factor for chronic diseases, and calorie restriction (CR) is a robust non-pharmacological intervention that can extend health span in multiple species. Alternative splicing (AS) generates multiple RNA isoforms from a single pre-mRNA and becomes dysregulated with age; intriguingly, prior work suggests that CR can attenuate age-associated splicing noise. What has remained unclear is whether AS responses to CR are coordinated across tissues and whether they scale with the level of restriction.

As an emerging branch of clinical medicine, microbiota medicine has attracted worldwide attention from clinicians, medical educators, patient communities, and industry. However, this developing field still lacks consensus on its fundamental principles as well as guidelines for clinical and educational practice. An expert panel was convened by the journal Microbiota Medicine Research at the 2025 CHINAGUT Conference to develop the principles and practice guidelines of microbiota medicine.

A new study published in Life Metabolism reports that a single post-meal blood biomarker, 1-hour postprandial SPARC (SPARC-1H), can predict who will benefit most from adopting a Mediterranean diet. The discovery provides one of the clearest examples to date of how precision nutrition can identify individualized dietary responses using a simple blood test rather than complex multi-omics models.

Glycine, a non-essential amino acid derived from serine, plays an increasingly recognized role in metabolic regulation. Epidemiological studies consistently show that reduced circulating glycine levels are associated with insulin resistance, type 2 diabetes (T2D), and obesity across diverse populations. However, the molecular mechanism linking glycine to insulin production has remained incompletely understood, limiting therapeutic applications.

Metabolic dysfunction-associated steatotic liver disease (MASLD), a spectrum of liver conditions ranging from simple steatosis to steatohepatitis (MASH), fibrosis, and cirrhosis, represents a global health epidemic with no approved pharmacotherapies.

The liver plays a central role in maintaining systemic energy homeostasis during fasting by mobilizing lipid reserves, a process often accompanied by transient hepatic steatosis. Dimethylarginine dimethylaminohydrolase 1 (DDAH1), a key enzyme metabolizing asymmetric dimethylarginine (ADMA), has been shown to protect against NAFLD under nutrient-overload conditions. However, its role in the physiological context of fasting remained elusive.

Emerging evidence reveals that dysregulated autophagy, particularly the selective degradation of lipid droplets (lipophagy), is crucial to maintaining hepatic lipid balance, yet how its activity is regulated under different metabolic conditions has long been an open question.

On 1 August 2025, China's GBZ 337–2025 Diagnostic Standard for Occupational Post-Traumatic Stress Disorder came into force.1 For the first time, post-traumatic stress disorder (PTSD) among emergency responders, including police, firefighters and medical personnel, has been formally recognised as an occupational condition, eligible for compensation under the country's occupational injury system. This move marks a significant institutional acknowledgement that psychological trauma can be as disabling and deserving of protection as physical injury. Far from an isolated policy decision, GBZ 337–2025 marks a milestone in decades of evolving scientific understanding, public awareness and policy development, shaped by the lived experiences of natural disasters and public health emergencies in China.

FIU researcher continues studying the long-term effects of toxic exposures and psychological trauma as responders age.

A research team set out to discover how the apparent temperature, or “feels like” temperature, over the ocean differs from the apparent temperature on land and found that a pronounced land-sea contrast is evident.
